Noctua's DH-14: Air Cooling Keeps Up With Liquid?

6 thumbs up
Noctua has a reputation for excellent fans, and our experience with the NF-P12 and NF-P14 that ship with the NH-D14 was first-rate. The company also shipped us a pair of its NF-F12 PWM ultra-quiet fans.

The NF-F12 PWM fan series. Note the stator vanes with their curved notches

These new designs incorporate a number of technologies aimed at improving cooler efficiency and reducing noise. At the heart of the new design is a technology Noctua calls Focus Flow. Focus Flow uses stator vanes to vary air compression across the fan blades as they turn.

This diagram from Noctua is meant to illustrate the benefit of using Focus Flow, but it also demonstrates why adding a second fan to a conventional liquid cooler in a push/pull configuration (as the H100 and H80 do) yields only a small additional improvement. Forcing air over a heatsink creates an area of low pressure directly behind it; the air swirling through this area is called an eddy. Adding a second fan without accounting for the additional turbulence means that a majority of the potential cooling benefit is canceled out.

The company's website details each and every improvement its made to the NF-F12 PWM, including its adoption of a new PWM. We swapped the DH-14's fans for the pair of NF-F12's in our review; comparative results are included in the benchmark data. The DH-14 may be made by Noctua, but it's not necessarily an ideal platform for this type of test. The heatsink's standard fans come with pre-attached clips; we had to finagle the NF-F12's into place to get them to fit. In addition, the extra dampening material around the edges of the NF-F12 fans give them a bit less room when wedged between the two heatsinks.

So, it's expensive and somewhat difficult to install. How's it perform?

These guys have a fantastic reputation, and this cooler is considered by many to be the best in Air Cooling.

One thing that I noticed was that you have the cooler pointed straight up, with the air intake quite close to the video card. Most of the enthusiast's installations of this cooler that I've seen in the past have the cooler pointed so that the air flows out the backside of the case. (pointed right to left)  They say that the cooler's performance is increased by doing it this way.

Noctua has a kit available for mounting some of their coolers 90 degrees from stock orientation, but this cooler may be able to do that right out of the box.

Thats a BIG HS, I use to have a noctua HS back in the day it worked quite well.

Noctua coolers are always the best kind of coolers but they've always been known to be big and clunky, and for good reason. I have never had the space in order to justify having one but I always see the results in these CPU coolers and I'm reminded as to why Noctua is so popular/good. This is no exception; the latest in the long line of Noctua coolers proves itself without really trying and even though it's so massive and hard to install, it's worth it for superior temps and superior noise.

This company Phanteks is giving Noctua a real run for their money.

See Here.

It's said that they actually beat the NDH-14 cooling performance because of a coating they have put on the fins. They come in four colors too.

Thanks for the solid and enjoyable review ,, I suppose if I were to honestly have a choice between the the Noctua DH-14 and the Phanteks in the neils post, I would choose the Phantek ,simply because they may perform a bit better and having the choice of colers would seal the deal for me.
